Yes, Because if you draw this into a graph it comes has a straight line going thought the origin
2x^2+2x-40=0
2x^2+10x-8x-40=0
2x(x+5)-8(x+5)=0
(2x-8)(x+5)=0
2(x-4)(x+5)=0
x=-5 and 4
If you graph it, the zeros are just the values of x when the curve meets the x axis...
Step-by-step explanation:
Weight of fish Eric bought
= Weight of fish at first - Weight remaining
= 7/8 lb - 1/2 lb = 3/8 lb.
Number of fish Eric bought
= (3/8 lb) / (1/64 lb)
= (24/64 lb) / (1/64 lb)
= 24.
Hence Eric bought 24 fishes.
It's the bottom one. 20 dollars has to be less than or equal to the amount. you cannot spend more than $20
Answer:
PEMDAS
[(30+6)-3^2] ÷ by 9·2
[(30+6)-9] ÷ by 9·2
[(36)-9] ÷ by 9·2
(27) ÷ by 9·2
Division comes first in this equation. Multiplication & Division goes from left to right when using PEMDAS. Same thing goes for Addition & Subtraction.
[(27) ÷ 9] · 2
(3) · 2
Answer: 6
Hopefully that made sense!
